The Voigtlander Nokton 42.5mm f/0.95 for Micro 4/3 is an ultrafast, short-telephoto prime lens that is designed specifically for extremely low-light shooting, particularly for filmmakers. It is a great length for portrait shooting. You can choose between having traditional aperture control or a stepless, de-clicked method suitable for video. The build is top quality with an all-metal barrel and very smooth fully manual focusing. This lens is ideal for fine art photography, low-light photography of all kinds, and videography.
